Trivia

For an unknown reason, Venonat is able to learn Flash in Pokémon Yellow, but not in Generation II (it regained that ability in Pokémon Ruby and Sapphire).

Origin

In spite of Venonat's name it is not similar to a gnat in size, physiology or behavior, other than on its compound eyes. It is likely also based on a mite, which also sucks blood, is round, and have a pincer-like mouth.

Name origin

Kongpang is possibly a combination of こんちゅう konchū (insect) and pang (the sound that a radar makes, referring to its radar-like eyes). It could also be a shortening of コンパウンド アイ compound eye, both referring to its eyes and its ability.
